流媒体指在Internet/Intranet中使用流式传输技术的连续时基媒体。P2P智能节点是在不同类型的链路(时延/带宽)下,由节点实时对网络环境进行监视、评估和调节,实现网络的自优化和自恢复,尽可能提高应用的有效性;由节点实现端到端的流媒体数据传输,一条路径不好可以自动切换到另一条路径,或使用多条路径共同传输,以保证服务质量(QoS,Quality of Service)。传统的P2P模式流媒体系统的数据接收端节点,设置一个单级缓存区,一般采用以最快数据传输速度填满一个缓存区的简单策略。为了实现流媒体内容实 Streaming refers to the continuous time-based media that uses streaming technology in the Internet / Intranet. Under different types of links (delay / bandwidth), P2P intelligent nodes monitor, evaluate and adjust the network environment in real time to realize self-optimization and self-recovery of the network and improve the application’s validity as much as possible. To achieve end-to-end streaming media data transmission, a path is not good can automatically switch to another path, or use multiple paths to transmit together to ensure quality of service (QoS, Quality of Service). The data receiving end node of the traditional P2P mode streaming media system sets a single-level buffer area, and generally adopts a simple strategy of filling up a buffer area with the fastest data transmission speed. In order to achieve the real content of streaming media
